T0 all whom z't may concern:

Be it known tha.t I, HENRY D. ZEHRBACH, a. citizen of the United Stabes,residing at Bluflton, in the eounty of Allen and State 0f Ohio, haveinvented 9. new and useful Casting, of which the following is aspecification.

'l bis invention relates 00 sight glasses f0r cream separators and hasfor its object to provide a comparatively simple and inexpensive device01 this charaeter especially designed for attaehment t0 gravity creamseparators to permit inspection of the 0011- tenos 0f the milkcontaining vessel cluring the separatin process.

A further 0 ject of the invention is t0 provide a frame 01 castinghaving a. seat 011 one side thereof for the reception 0f a. sight gla.ssand provi0lecl at ios lower end with an opening the interior Walls ofwhich are threaded for enga erneut with a faucet.

A furt er object is 110 provide a link for retaining the sight glass toits seat in the casv ing, and means for loeking the link a.gainstaceidental displacement.

Further objects and advantages Will appear in the following description,it being understood that various ehanges in form, proportions anal minordetails 0f construction may be resorted 130 within the scope of theapgended claims.

In t e aqcompanying drawings f0r ming a part 0f thisspecificationz-Figure 1 is a. lon gitudinal sectional view 0f a combinedsight glass and faucet seat constructed in accordance with my invention,showing the same in position 0n a cream separator. Fig. 2 is a fr0ntelevati on of the same With the faucet removed. Fig. 3 is a. detailperspective view 0f the sup orting frame 01 casting detached, the sightg ass ancl retaining link being shown detached from the casting.

Similar numerals 0f reference indicate 001- responcling parts in all ofthe figures 01 the drawings.

The sight glass forming the subject matter of the reseno invention isprincipally designed or attaehment 110 that dass of cream separators inWhi0h a single vessel is employed f0r conta.ining the milk and water,anci in Fig. 1 of the drawings is shown in in which 5 designates theliquid containing vessel having an inclined bottom 6 and provided with adepending supporting flange 7.

The device consists 0f a supporting frame er casting 8 having adapted tobear against the exterior Wall 0f the recepacle 5 and provi0led with alateral extension 10 which projects within the recepoaele 5, es shown,alle metal around the opening in the receptacle 5 being bent laterallyand sol0lered 01 otherwise rigidly secured o0 the extension 10, asindicated ab 11.

Projeeting inwardly from the casting 8 at the extension 10 is a flange12 whioh forms 9. seat for a sight glass 13, t-he lauter being retainedin osition 011 the flange 12 by a hollow frame 01 link 14.

Formed in the end Walls of ehe extension 10 are recesses 15 in which aresolderecl o1 otherwise secured suitable locking lugs 16, the terminals01 which are adapted '00 be bent downwardly in conta0t with the link 14,thereby t0 retain seid link in engagement with the glass 13 and preventaecidental dis placernent 0f the latter during transportation ershipment 01 the separator.

The l0wer encl'of the easting 8 is curved 01" roundecl ab 17 andprovided with a centrally disposed 0 ening 18, the interior Walls efwhioh are t 11eacle0l for engagement Wibh the correspondingly threadedterminal 01 0 fau0et 19.

The bottom 01 the receptacle 5 at the threadecl end 01 the faucet isdeflected downwardly at 20 so as t0 permio the cream in the reeeptacle 5t0 be readily drawn off through the faucet when ehe latter is moved toopen position.

The face 0f the casting 8 at tl1e eurved portion thereof is out away t0produce horizontally alined recesses 21 a.da ted o0 receive thereinforcing beacl 22 0'l? t e bottom 6, thereby t0 assist in retainingthe castingin proper osition 011 the containing vessel.

In assembling the several parts an opening is first formecl in thereceptacle 5, after Wl1i0h the casting 8 is introduced within theopening With ehe flange 9 bearing against the exterior Walls 01 thereeepta.cle and with the extension 10 projecting within the saidreceptacle, as best shown in Fig. 1 of the drawings. The glass is thenpositioned 011 the flange 12 and the link 14 moved laterally inengagement with the rear face 01' ohe glass, afoer which a. smallquantity 0f putty, cement 01 other adhesive material is introducedwithin a. margmal fiange 9 having a flange adapted exte1ior Wall 0f allevessel and provided With the seating r ecess and tl1e lugs 16 prssec'llaterally agamst the reaf fa :e 0l ehe link, thereby t0 retain the linkand sightglass in position on the casting. After the parts are thusassembled, the faucet 19 is screwed into the opening 18 in ehe usualmanner.

It will thus be seen that there is provided a combined sight glass seatand faucet seat capable 0f being readily attached to a separat0remploying a single liquid conoaining Vessel and in which liability ofbreakage of the sight glass is reduced to a minimum, and a firmanchorage formed for the fauceo, thus obviating the necessity ofsoldering the faucet 0n the containing vessel and the employment ofmetal gages heretofore used 0n this dass of cream separators.

Having thus described the invention what is claimed is:

l. The combination With a single Wall liquicl containing vessel, of asight glass frame permanently secured t0 and projeoting Within thevessel and provided With an Opening a faucet seated in Said opening, asight glass carried by ehe frarne, and means for locking the glassagainst accidental displacement.

2. The combination With a single Wall liquid containing vessel, 0f asight glass frame having a marginal flange arrangecl o0 bear against theexterior Walls of the vessel and providecl With an extension projectingwithin and pe'rmanently secured t0 t e receptacle, said frame beingprovided with an elongated seat and having a threaded opening formed inone end thereof, a faucet threaded in said opening, a sight glassengaging the seat, and means for locking the sight glass againstaccidenfal displacement.

8. The combination with a Single Wall liquid containing vessel, 0f asight glass frame to bear against the an extension projecting mithinsaid vessel and provided With an opening, a faucet seatecl in saidopening, a sight glass carried by the frame, a link bearing against theglass, and lugs engaging the link for locking tl1e latter in engagementwith tl1e glass.

4. The combination Wil1 a single Wall liq uid cc ntaining vessel, 01 asight glass frame permanently secured to and projecting Within thevessel and provided with an opening, a faucet seated in said opening, asight glass carried by the frame, a link bearing against the sightglass, and lugs securecl t0 the frame and adapted to be bent laterallyin contact with the rear face 0f the link for locking the latter inengagement with the sight glass.

5. The combination With a liquid Containing vess al ha'vihg an opningformed therein, a sight glass frame seated Within said open ing andhaving its front portion provided l With a laterally extending fiangearranged to l bear against alle exterior Wall of ehe vessel and its 1earportion formed Wlllll an extension projecting v.ithin the receptacle,the material forming the vessel being bent laterally and secured to theextension of the frame at said opening, a sigho glass carried by theframe, a faueet iercing the lower encl 0f the frame and comrnunicatingWith the interior 0f the vessel, and 1neans for locking the sight glassagainst accidental displacement.

6. The combination vrith a liquid conoaining vessel having a reinforcingrib, of a sight glass frame having a marginal flange arranged t0 bearagainst tl1e exterior Wall 0f the vessel and provicled with a lateralextension projecting within the Vessel, tl1e lower and of alle framebeing provided with a threaded Opening andhaving horizontally alinedrecesses formed therein at said opening and adapted to receive thereinforcing rib of the receptacle, a faucet threaded in said opening, asight glass carried by the frame, a link bearing against the sightglass, and lugs carried by the frame and acla ted t0 be bent into (angagement with tl1e ink.

7. The combination Wi'll a liquid containing vessel, 0f a sight glassframe having a marginal flange arranged t0 bear against the exteriorWall of the receptacle and provided with an inwardly extending flangeconstituting a seat, obere being a threacled opening formed in one endof the frame, a sight glass resting 0n the inwardly extendecl flange, alink bearing against alle sight glass, there being recesses formed inalle opposite ends of the frame at the inwardly exten'ding flange, lugsseated in saicl recesses and adapted to be bent in contact With thelink, and a faucet having one and thereof threaded for engagemenb vdththe threaded Walls 0f the opening and communicating With the interior ofthe vessel.

In testimony that I claim tl1e foregoing as my own, I have heretoaifixed rny signature in the presence 0f tWo witnesses.
